Session still valid if user returns?
Once again, i have I question, to which I found no answer: If the user leaves my wicket application and navigates to another website and returns to my wicket application within a few minutes. Is his previous session still valid?
Re: Session still valid if user returns?
Yes, if a) the session hasn't expired yet (there's inactivity period after which session expires, usually set to 30 minutes) b) user hasn't closed the browser - the session cookie is still valid or c) session id is encoded in URL. -Matej On Fri, Sep 5, 2008 at 9:47 AM, Liz Huber [EMAIL PROTECTED] wrote: Once again, i have I question, to which I found no answer: If the user leaves my wicket application and navigates to another website and returns to my wicket application within a few minutes.

Re: Assert that all models are detached at the end of the request?
For the sake of completeness, here is the solution I am currently
using. It uses,
as suggested by Martijn, a custom request cycle and a modified version
of
SerializableChecker. You have to install the custom request cycle in
your application
using
@Override
public RequestCycle newRequestCycle(Request request, Response
response)
{
return new CustomRequestCycle(this, (WebRequest) request,
(WebResponse) response);
}
Hope this helps others, too!

Re: Problem with multiple browser windows and locked page maps
Hi Johan,
I've seen the code in WebPage.onNewBrowserWindow(). The thing I'm having a
problem figuring out is where to hook in this code. I can't see that I can
do this in the constructor of a page as you suggest. In the constructor the
page hasn't been fully constructed yet so I can't see that I could clone the
page and redirect to it in the way that onNewBrowserWindow does. I've also
had a look in wicket.Session to see if there's a place that I can hook in
this extra check but I can't see how. Partly because all the relevant
methods are final so can't be overridden...
I tried to patch our version of Wicket to get a workaround for this. I
added the following to Session.newPageMap(String name):
public final IPageMap newPageMap(String name)
{
if (name == PageMap.DEFAULT_NAME) {
name = createAutoPageMapName();
log.debug(Allocated new page map name: + name);
}
...the rest as before...
}
This seems to solve the problem, but I don't know if this as other side
effects. If this is basically a sensible fix, would it be reasonable to add
a hook for doing this in a cleaner way, e.g. adding a call in newPageMap()
to a new method getPageMapName(name), that in the default implementation
just returns the argument, but could be overridden to do the above?

First try to look at the newbrowser window check that we have in webpage.
Dont know if you can all do those things (clone the page and set
another pagemap)
What you could do is int the page const check pagemap, if default then
create the same page as you are on but then with a different pagemap
and throw a restartresponse exception.

the

other page details in order to redirect to the same page? Sorry if I'm
being dim here, but some more details would be greatly appreciated.
And yes, pages shouldn't take a long time to load, it's just that in some

Yes your observation is exactly what i described.
What you can do is for example check in the constructor (with pagemap
param) or in onbegin request (before render) of a page, if the pagemap
is the default, if it is create the same page with a new pagemap and
redicect to that one.
Whay you want is that the default pagemap is never used, by defaul all
pages are going into that
But you should check if you really want long running processes like
that!

Thanks for your answers, Matej and Johan.
Matej: we are running with multi-window support on, and store

most of the time.
Johan: I've been stepping through the Wicket code and studying the
docs
to
understand how it deals with new windows, and I think I'm starting to
understand what's happening, and your comments about default page
maps.
Basically what seems to be the case is that the inital window in a
session
never receives its own page map name, it stays on the default one.
This
means that this initial window is indistinguishable from a brand new
window
that hasn't yet had a page map name allocated and been redirected to a
page
with this set. I've done some tests which seem to confirm this
hypothesis:
- I open an initial browser window on my application (window 1)
- I open a second window in the same session (window 2)
If a start a long-running operation in window 1, any new windows
created
will lock until window 1's operation has been completed.
However, if I start the long-running operation in window 2, I can open
new
windows to my heart's content and they will not block.
Does that make sense, is this an accurate description of the problem?
It seems odd that the initial window is never allocated a page map
name,
which leads to this assymtry between windows. Is this something that
can
be
fixed? Or even better, can I do something my side in order to force
any
window/page map opened against a session to have a unique name
allocated?

Problem sharing model between 2 panels
Here is the problem I have a Parent panel which swaps in and out a Display panel and an Update panel (these are basically 2 views, read-only and read-write, of a users details). To enable any changes by the Update panel to be seen by the Display panel, I have both panels pointing to the same model, which in turn wraps the same user object. However, the Update panel uses a form to affect changes. This form also points to the same Model / Object and herein lies the problem the form maintains the same model throughout requests (as expected) BUT after debugging I found that it seems to be creating a different underlying model-object for each request. Therefore, while both my panels point to the same Model / Object the form is making changes to a different Object! Long story short after swapping the panels post-Update the changes are not seen by the Display panel. Is this form behaviour what you would expect to see? If so, is there a more elegant solution than just manually copying the changed fields between model-objects or grabbing the changed user object from the db again? Any help, very much appreciated.

Re: wicket-like framework to complement wicket?
first off, i admit i didn't know too much about domdrides.
so it seems i was talking about the entity part. e.g. extend
UuidEntity in your domain, that is orthogonal to gluw. concerning
domdrides repository approach, as a quick idea i can imagine
implementing gluw in an adapter pattern manner. not sure about generic
params though.
/**
* A Gluw-based implementation of a person repository.
*/
public class GluwPersonRepository extends
GluwRepositoryPerson,String implements PersonRepository
{
public GluwPersonRepository()
{
super(Person.class);
}
}
public abstract class GluwRepositoryEntityType extends
EntityIdType, IdType extends Serializable extends
gluw.repo.RepositoryImplEntityType extends EntityIdType implements
RepositoryEntityType, IdType
{
protected HibernateRepository(ClassEntityType entityClass)
{
super(entityClass); // will have to change constructor's package scope
}
// adapt existing methods signatures to super methods
// new methods such as contains() not found in gluw.repo.Repository,
implement by calling getDB() which provides an instance of ODB
(neodatis)
// - analogous to spring's HibernateDaoSupport
}
note you won't be taking advantage of the ootb
gluw.repo.RepositoryEntity if you use domdrides approach
(obviously). do you think integration is feasible?
francisco
ps: i should re-examine the way i'm handling getById(Serializable id).
as i don't force the end user to extend any particular domain base
class, i use a string/reflection-style ODB query -- which can cause
trouble if the id field is not present. will have to evaluate
tradeoffs of both approaches

Making a Behavior that adds a script after a component?
I have a couple of behaviors that add javascript to the header of a
document, to change attributes or add event scripts to components (using
jquery onready, but that's not the point). This all works fine. There is
just one problem: when I use such components in an ajax
request/response, it won't have the javascript added attributes anymore,
because the component gets replaced by the wicket ajax call.
I'm looking for a way to make the behaviors add the necessary javascript
to add the attributes again, when an ajax response is created. E.g. a
way to let behaviors add a script to every ajax response, or let them
add script tags after the rendering of the component. Is there a way to
do this in Wicket?
I know I could make a custom panel/component that just has an extra
script tag, but that's far to intrusive, and makes it really difficult
to make different combinations of these behaviors.
Example behavior class:
public class DatePickerBehavior extends AbstractBehavior {
private String createOnReadyScript(String markupId) {
return $(document).ready(function(){\n +
createPickerScript(markupId) + \n});;
}
private String createPickerScript(String markupId) {
return $('# + markupId + ').datepicker();;
}
public void bind(Component component) {
super.bind(component);
component.add(new HeaderContributor(new IHeaderContributor() {
public void renderHead(IHeaderResponse response) {
response.renderJavascript(createOnReadyScript(component.getMarkupId()),
null);
}
}));
//Is there a way to instead of contributing to the header, add
the script to the document body after the rendering of
// the component itself.
//Or a way to add a script to every ajax request?

In the tutorial I am following, the response page shows an exception message containing a WicketMessage describing the actual error which is entitled Unexpected RuntimeException. I have followed the author's steps but I don't get this nice exception message. Does anyone know if I am missing something in my configuration of Tomcat or in my deployment descriptor?

I have a couple of behaviors that add javascript to the header of a
document, to change attributes or add event scripts to components (using
jquery onready, but that's not the point). This all works fine. There is
just one problem: when I use such components in an ajax
request/response, it won't have the javascript added attributes anymore,
because the component gets replaced by the wicket ajax call.
I'm looking for a way to make the behaviors add the necessary javascript
to add the attributes again, when an ajax response is created. E.g. a
way to let behaviors add a script to every ajax response, or let them
add script tags after the rendering of the component. Is there a way to
do this in Wicket?
I know I could make a custom panel/component that just has an extra
script tag, but that's far to intrusive, and makes it really difficult
to make different combinations of these behaviors.
Example behavior class:
public class DatePickerBehavior extends AbstractBehavior {
private String createOnReadyScript(String markupId) {
return $(document).ready(function(){\n +
createPickerScript(markupId) + \n});;
}
private String createPickerScript(String markupId) {
return $('# + markupId + ').datepicker();;
}
public void bind(Component component) {
super.bind(component);
component.add(new HeaderContributor(new IHeaderContributor() {
public void renderHead(IHeaderResponse response) {
response.renderJavascript(createOnReadyScript(component.getMarkupId()),
null);
}
}));

AjaxFormComponentUpdatingBehavior(onchange) does not work when added to a FormComponentPanel
Hello all,
I created a Component called TimePanel which is a FormComponentPanel
containing two DropDownChoices. As you may have guessed from the components
name, its used to input time. It is intended to be used with Jodas LocaTime as
a ModelObject. One DDC is for hours, the other one for minutes. It is very
similar to the Time part of the DateTime Input example from WIA.
Now what i want to achieve, is that this Panel can be used with
AjaxFormComponentUpdatingBehavior(onchange) like any non-composite form
component:
timePanel.add(new AjaxFormComponentUpdatingBehavior(onchange)
{
@Override
protected void onUpdate(AjaxRequestTarget target)
{
target.addComponent(getForm());
}
});
I expected problems, mostly because the enclosing div (the panels container)
gets the onchange listener added. but to my surprise, an js event was
generated when i changed the selected value in one of the select elements, and
ultimately my TimePanel's convertInput() Method was called. My convertInput()
looks like this:
@Override
protected void convertInput()
{
Integer hour=m_hourDropDownChoice.getConvertedInput();
Integer minute=m_minuteDropDownChoice.getConvertedInput();
setConvertedInput(new LocalTime(hour,minute));
}
but both DDCs give me nulls as their convertedInput. They dont have any raw
input either. Digging a little further i discovered why: ofcourse the
timePanels, and not the DDCs, inputChanged() and getInputAsArray() methods are
called when the event is triggered. they try to get a value from the request
via the panels id, which of course results in null.
Now my question is: Is there a best practice for what i try to achieve? Or is
there already an AjaxBehaviour which does what i want?
thank you for reading,
lutz
Re: Problem sharing model between 2 panels
the model that the display panel should be a loadable detachable model so it loads data from the database on render the model that the update panel uses should load the changes, edit them, and save them to the database. that way everything is in sync. when the form submits it clones the model object, that is done for versioning reasons, but it is the clone that is kept...the reference to the actual model object should not be changed. -igor On Fri, Sep 5, 2008 at 6:05 AM, Neil McT [EMAIL PROTECTED] wrote: Here is the problem I have a Parent panel which swaps in and out a Display panel and an Update panel (these are basically 2 views, read-only and read-write, of a users details). To enable any changes by the Update panel to be seen by the Display panel, I have both panels pointing to the same model, which in turn wraps the same user object. However, the Update panel uses a form to affect changes. This form also points to the same Model / Object and herein lies the problem the form maintains the same model throughout requests (as expected) BUT after debugging I found that it seems to be creating a different underlying model-object for each request. Therefore, while both my panels point to the same Model / Object the form is making changes to a different Object! Long story short after swapping the panels post-Update the changes are not seen by the Display panel. Is this form behaviour what you would expect to see? If so, is there a more elegant solution than just manually copying the changed fields between model-objects or grabbing the changed user object from the db again? Any help, very much appreciated.

Re: Render html with Wickettester inside webapp locks page

Re: Assert that all models are detached at the end of the request?
Could you perhaps use an aspect for this? On Thu, Aug 28, 2008 at 4:57 PM, Kaspar Fischer [EMAIL PROTECTED] wrote: Is there an easy way to assert that all models are detached at the end of the request? It does not look so easy to check this as models do not have common base class where one could register them for a check... I often use an additional model in a component and store it as a member field; if I forgot to detach() this model in the onDetach() handler, I would have a dangling model. That caused me quite some trouble once and I want to avoid it in the future.

How to trigger Ajax event from client side javascript?
Hi,
I'm trying to trigger OnChangeAjaxBehavior on an HiddenField (or TextField)
change from client side javascript.
Here is the code in html:
function change(){
var change = document.forms[0].changed.value;
if(change != true) {
document.forms[0].changed.value = true;
}
}
input type=hiden wicket:id=changed/
in wicket:
Form form = new Form(form);
add(form);
final HidenField changed= new HidenField (changed);
form.add(HidenField);
final Label label = new Label(selectedValue);
label.setOutputMarkupId(true);
form.add(label);
OnChangeAjaxBehavior onChangeAjaxBehavior = new
OnChangeAjaxBehavior() {
@Override
protected void onUpdate(AjaxRequestTarget target) {
target.addComponent(label);
}
};
changed.add(onChangeAjaxBehavior);
Any help will be very much appreciated.

Re: DateField throwing runtime error in IE only
Hi, Did you or anyone found the solution to this? I am having the same problem in IE7 on a ModalWindow (implemented as Panel) with a DateTextField and a DatePicker attached to it. I noticed that it works for the first time when there is no date in the date field...but after date is selected and if user wants to change the date it does not work...Calendar does not come up. If you remove date from the date text field and click on calendar again then Calendar comes up but does not respond to date selection...and you cannot close the calendar by clicking [x].It also shows unknown runtime error line 2993. Did anyone face the similar problem?
